DRAFT-HIGGING FOR RAILWAY-CARS.

' State of New York, have invented certain new and useful yImprovementsin Draft,

Rigging for Railway-Cars; and I do hereby declare the following to be afull, clear, and. exact description of thesalne, reference be ing had tothe accompanying I drawings, forming part of this specification.

This invention relates to draft rigging for railway cars, the objects ofthe invention being to make a structure of maximum etliciency which willoccupy a very limited space and which, at the same time, may beassembled on a car at a minimum expense.

Theximproved rigging of the present invention 'provides for the proper{ieXibilit-y of mov-ement of the cars with relationto each otherin avery compact space without seriously "cramping or distorting any oftheparts of the rigging, and, by reason of its compact-ness, the Vdevice isparticularly adapted for use in cars having no platforms and with littleoverhang beyond the bolsters, It will be understood, however, that thefeatures ofthe invention may be embodied in draft rigsuch as ore carsand the like.

ging for any type ofy car, wherein it is desired that a compact riggingof maximum efficiency be employed.

The invention consists in certain, novel. details of construction andcombinations and arrangements of parts as will. be .herein afterdescribed and pointed out particularly in the-appended claims.

In the accompanying drawingsfe Figure -1 is a rigging 'constructed inaccordance with the present improvements. f Fig. 2 is a longitudinalsection of the Fig. 3 4is a front elevation of the rigging. Fig., a isa`section on the line 4.-4 of Fig. 1.

this member is` located behind the follower plate F which occupies aposition to the rear of the vertically lalined inner 4flanges bs of thecastings B, B and bridges the cou ler shank opening in the frontcastings ig. 2). Connected with the pin E are the side members g of adraft yoke G. Said draft yoke is preferably composed of a single bar ormember, substantiallyU-shaped and with its 'forward open end receivingthe shank C", and its rear closed end g passing around the bottom of thepressure resisting member. -The forward ends of the side members g ofthe yoke are provided with elongated slots g to receive the pin E, andto permit the rearward movement of the pin E 1n unison with the couplershank, it being under-` i with a washer and Cotter pin e', although thisrearward movement stood that durin remains stationary. Un-

The pin E may besecured to -its connected parts by providing it witha head e at one end and at the opposite end `any. other method ofpreventing slipping of the pin will besuicientfor'the purposes of...thepresent invention. Between the follower plate F and the rear 4endgof the draft yoke is the yielding pressure resisting', memberwhch, inthe present embodiment is of the type in my co4 by tapering verticalwebsmz. vertical web ms extends from the rear of the Y into engagementwith the wedge blog ks and also intoengagement with a tongue f on thefollowery plate F. ASaid wedge blocks are sultably recessed or slottedfor the `reception of the tongue f of the follower plate, aslmore fullyset forth in my said co-pending application. The wedge blocks H and thecenter wedge K augment the springl resistance'by frictional resistance,a feature'common to many patents heretofore granted this applicant. Itwill be understood that the pressure resisting member operates bothunder draft and buiiing stress, to absorb the strain in a manner'wellknown in the art. Under buliing stress, the' st-rain is transmitted tothe friction blocks by the follower plate F, the barrel L remainingstationary and the movement of the blocks is against the ieldingresistance ofthe springs within t e barrel. Under draft'stress, theAfollower -plate F remains stationary abutting against the verticallyalined inner llanges b of the frontstop castings, whereas, the barrelmoves, the strain being. .taken up by' the friction blocks and thesprings within the barrel.

Fixed between the 'sills A and positioned to the rear of the barrel Land-the rear end of the draft yoke G is the rear stop casting M.According to the present invention, this stop casting .is constructed ofsuch cross section as to impart maximum strain resisting properties tothe casting. The casting, which isv fram-ed' in between the .sills A, 1sprovided'with 'a front bumpingface m, of

somewhat less transverse dimension than the main rear' portion ofthecasting and connected with th'e rear side vertical webs m The central ibumping face m and is reinforced by transverse Webs m* which connect theopposite .sides of the central vertical web with the side webs m. Thecentral vertical web 'm3 is further reinforced by horizontal flanges m5extendingv alongfeach side of the web Yand l'preferably tapering fromthe rear of' the bumping face', into the op osite sides of the web, asshown in Fig.'1. he tapering Vertical webs m2 are respectivelyreinforced by inner horizontalilanges m5.

The :bottom of the spring barrel L is provided vwith a reinforcingmember N, this vbeing acasting or other suitable means for thickenn upthe bottom of thetbarrel. To avoid' ma 'ng a heavy section of metal the.reinforcing memberis provided with open- -l, as shown'fin Eig'.;2.
